HOUSTON -- As you work on your taxes this month, here's something to raise your hackles: Some of the world's biggest, most profitable corporations enjoy a far lower tax rate than you do--that is, if they pay taxes at all.
The most egregious example is General Electric ( GE - news - people ). Last year the conglomerate generated $10.3 billion in pretax income, but ended up owing nothing to Uncle Sam. In fact, it recorded a tax benefit of $1.1 billion.
Avoiding taxes is nothing new for General Electric. In 2008 its effective tax rate was 5.3%; in 2007 it was 15%. The marginal U.S. corporate rate is 35%.
